Answer:
29.) 141 mi/gal
30.) # of protons
Explanation:
29.) This is a double unit conversion. The equation is:
Because your original number (60.0) has 3 significant figures, you round to 141 mi/gal.
30.) The identity of an element is always determined by the # of protons. If the # of protons changes, it becomes a different element.

See explanation
Explanation:
In naming an alkane, the first thing we do is to obtain the parent chain by counting the number of carbon atoms in the chain.
When we obtain that, then we identify the substituents and number them in such a way that they have the lowest numbers. The compounds shown have the following names according to the order in which the structures appear in the image attached;
1. 2-methyl propane
2. 2,4-dimethyl heptane
3. 2,2,3,3-tetramethyl butane
4. 5-ethyl-2,4-dimethyl octane
